The Detection of Kiwifruit Sunscald Using Spectral Reflectance Data Combined with Machine Learning and CNNs

open access: yesAgronomy, 2023
Sunscald in kiwifruit, an environmental stress caused by solar radiation during the summer, reduces fruit quality and yields and causes economic losses.

Cranberry fruit epicuticular wax benefits and identification of a wax-associated molecular marker [PDF]

open access: yesBMC Plant Biology, 2023
Background As the global climate changes, periods of abiotic stress throughout the North American cranberry growing regions will become more common. One consequence of high temperature extremes and drought conditions is sunscald.

Linking Tissue Damage to Hyperspectral Reflectance for Non-Invasive Monitoring of Apple Fruit in Orchards [PDF]

open access: yesPlants, 2021
Reflected light carries ample information about the biochemical composition, tissue architecture, and physiological condition of plants. Recent technical progress has paved the way for affordable imaging hyperspectrometers (IH) providing spatially ...

Development of Molecular Marker to Detect Citrus Melanose Caused by from Citrus Melanose-like Symptoms [PDF]

open access: yesThe Plant Pathology Journal, 2021
It is difficult to distinguish melanose and melanoses-like symptoms with the naked eye because they appear similar. To accurately detect melanose symptoms caused by Diaporthe citri from melanose-like symptoms, we developed PCR-based specific primers ...

Mitigating the Adverse Effects of Semi-Arid Climate on Capsicum Cultivation by Using the Retractable Roof Production System [PDF]

open access: yesPlants, 2022
Capsicum (Capsicum annuum L.) belongs to the Solanaceae family and is an economically important vegetable crop. However, the crop is very sensitive to adverse weather conditions such as high temperatures and excessive sunlight, which cause flower and ...

Identification of Candidate Heat-Tolerance Genes in Maize by Integrating Linkage and Transcriptomic Analyses [PDF]

open access: yesPlants
With global warming, high-temperature stress has become a primary abiotic factor limiting maize yield and quality. Exposure to heat stress induces sunscald on maize leaves, which severely impairs photosynthesis and ultimately leads to yield reduction. In

Phytohormone Interaction Modulating Fruit Responses to Photooxidative and Heat Stress on Apple (Malus domestica Borkh.) [PDF]

open access: yesFrontiers in Plant Science, 2017
Sun-related physiological disorders such as sun damage on apples (Malus domestica Borkh) are caused by cumulative photooxidative and heat stress during their growing season triggering morphological, physiological, and biochemical changes in fruit tissues

SUNIndx: Visual identification of sun stressed-areas of the fruit using a reflectance index (Sun Index) from hyperspectral images to predict sunscald-risk postharvest on ‘Granny Smith’ apples

open access: yesSoftwareX
Sunscald is a postharvest peel disorder on apples and pears caused by sun stress during fruit growth. It has been shown that a newly developed sun index using wavelength associated with chlorophylls and carotenoids can be used to detect sun-stressed ...

Pre- and Postharvest Management of Sunburn in ‘Granny Smith’ Apples (Malus × domestica Borkh) under Neotropical Climate Conditions

open access: yesAgronomy, 2021
Sun damage on apples is attributed to the occurrence of high temperatures, incident radiation, and fruit and plant water parameters, all dependent on climatic conditions and management. The development of new production areas and climate changes increase
